1.C,关系代词,其实whose=the film “Tutanic”'s leading actor.
2.C,非限制性定于从句,此时which代表前面整句话
3.C,此句的先行词是the hours,后面l was taken goodcare of in that far away village句子完整,因此用关系词 when
4.A,记住situation下面用关系副词where,因为后面句子完整.
5.A,其实省略了that/which he explained 第五题是非常经典的题目,稍稍改变一个词就可以有多种选法,这里选A
6.D,相信你单词写错了,tired改为tried猜对,非限制性定语从句做主语,用关系代词who
不明白可以问我.
